The Office of the University Registrar at UNL has reported that CourseLeaf Section Scheduler (CLSS) and Curriculum Inventory Management (CIM) are currently down due to an issue applying an update. The vendor is working as quickly as possible to fix the issue. This is likely affecting these services at UNK and UNO as well. Authorized representatives from academic departments who have urgent class scheduling changes for Summer or Fall 2026 should email the registrar's office on the respective campus so they can make the update(s); note that this requires a more manual process and they appreciate your patience as they work through any requests.
